It was announced earlier this week that Kristin Chenoweth is the National Anthem singer at Candlestick Park. That would be Kristin Chenoweth, the New York Giants fan.

She’s made some nods to this fact on her Twitter feed over the past few days.

I looked a little further and found this transcript of a Jan. 25, 2010, interview with Kathie Lee Gifford on “Today” — a few days before the Super Bowl between the New Orleans Saints and Indianapolis Colts.

GIFFORD: Now, over the weekend, as you–you might have known there were a few football games. Are you a big fan?

CHENOWETH: I am, but you know, I’m a Giants fan.

GIFFORD: Well, slap me, baby.

CHENOWETH: All right.

GIFFORD: But neither–we weren’t in it this year.

CHENOWETH: I know.

GIFFORD: We had our chance.

CHENOWETH: I know.

GIFFORD: I was very happy for the Jets going into the playoffs.

CHENOWETH: Me too, and representing New York.

Well, slap me, baby. A Giants fan will be singing the anthem on the 49ers home field.

But shouldn’t the home team 49ers have a hometown performer? Especially in an area where there’s no shortage of talented high-profile choices?

I’m guessing/hoping that the home team has little or no say over the National Anthem singer in the playoffs, and the performer is booked by the television network. (I sent an e-mail to my Chronicle colleague and talented 49ers beat writer Eric Branch to see if he knows.) I can’t imagine the 49ers would bypass so much talent in the area to pick a supporter of the opposing team to perform the song.

I’ll be at the game later today as a fan. Follow me on Twitter @PeterHartlaub — I’ll be the first to tell you if Chenoweth shows up on the sideline in an Eli Manning jersey.
